LG Electronics' OLED TV on display at a prestigious industry tradeshow had shown signs of prominent burn-in, ZDNet has learned.
At the SID Display Week 2018 in May at Los Angeles Convention Center, LG's OLED TV and Samsung Electronics' QLED TV were displayed in tandem by Nanosys, a quantum dot developer, at its booth.
The OLED TV was a 65-inch 2017-model purchased by Nanosys only two to three weeks prior to the event at a third-party store.
The TV was turned on for eight hours a day during the tradeshow and showed signs of burn-in at its top right corner immediately on May 22, the first day of the three-day tradeshow, according to multiple eye witnesses.
On the second day of the show, the problem became more noticeable and the Familytime logo that was on display was left permanently at the top right corner, they said.

Officials of LG Display, which also had a separate booth at the tradeshow near the entrance, visited the Nanosys booth multiple times after the problem emerged and made inquiries to the company on the TV, they added.
The TV at most ran 50 to 60 hours prior to being displayed at the event.
